T 0 all whom it may concern:

Be it known that 1, JOHN F. SLAPKA, a citiz'en of the United States, and a resident of the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Bottle Closures, of which the following is a specification.

My invention relates to improvements; in

bottle closures and has for its" object the provision of an improved. device of this character, of simple construction, efficient in use and which may be readily attached to or removed from the mouth of a bottle such as a milk bottle. j

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings forming a part of this specification, and in which,

Fig. 1 is a side view of theupper portion of a milk bottle illustrating a closure embodying the invention and shown in position of use;

Fig. 2 is a View of the closure taken at right angles to Fig. 1;

Fig. 3 is a top plan view of the closure, and

Fig. 4: is a section taken on line L-t of Fig. 3.

The preferred form of construction as illustrated in the drawings comprises a suitablecover plate 5 preferably made of aluminum or other noncorrosive metal and provided at its outer end with a depending flange 6. A substantially U-shaped spring clamp 7 is secured to the lower edge of the flange 6, there being heads 8 struck from said flange to contact with the, upper edge of said clamp and the lower edge 9 of said flange being turned upwardly about said clamp to secure the same in place. The clamp 7 is secured to the flange 6 at a slight angle to the cover plate 5 as indicated in Fig. 4 and whereby when the cover plate is secured in place on the milk bottle as indicated in Fig. 1 the cover plate 5 will be drawn downwardly into snug contact with the mouth of the bottle owing to the wedging action on the lip of the bottle.

An upwardly swinging lid 10 is secured to the inner edge of the cover plate 5, said lid and cover plate each occupying substantially one-half of the mouth of the bottle. The

lid 10 is provided at its edges with lugs 11 engaging through openings in perforated ears 1 2 turnedupwardly from the edges of the cover plate 5 and whereby a simple pivotal connection is effected. The lid 10 I is, alsov provided with a finger piece 13 having a depending stop flange 14 so arranged. asto limit the upward swing of the lid to prevent passage of the vertical as indicated in dotted lines in Fig. 1 and whereby it is insured that the lid will always close when released through gravity.

By this arrangement a simple and effectivebottle closure is provided'which can be manufactured at small cost and readily applied to or removed from the bottle mouth.

While I have illustrated and described the preferred form of construction for carrying my invention into efi'ect, this is capable of variation and modification without departing from the spirit of the inven-. tion. I, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.

Having described my invention what I claim as new and desire to secure by Letters Patent is:

1. A bottle closure comprising a cover plateto rest on top of the bottle mouth; a spring clamp below said plate to embrace the bottle neck below a bead thereon, said clamp and plate converging toward each other; and a swinging lid on said cover plate, substantially as described.

2. A bottle closure comprising a cover plate torest on top of the bottle mouth; a springclam below said plate to embrace the bottle neck below a bead thereon, said clamp and plate converging toward each other; a swinging lid on said cover plate; and a finger piece on said lid to contact with said cover plate, to prevent swinging of said lid beyond the vertical, substantially as described.

3. A. bottle closure comprising a cover plateto rest, on top of the bottle mouth; a depending flange at the outer edge of said cover plate; a substantially U-shaped spring clamp secured to the lower end of said flange,

. the lower end of said flange being bent upwardly around said clamp and there being beads struck from said flange to contact with. the upper edge of said ,clamp, and said clamp and plate converging toward each other; and a swinging lid on said cover plate, substantially as described.

4. A bottle closure comprising a cover plate to rest on top of the bottle mouth; a depending flange at the outer edge of said cover plate; a substantially U-shaped spring clamp secured to the lower end of said flange, the lower end of said flange being bent upwardly around said clamp and there being beads struck from said flange to contact with theupper edge of said clamp, and said clamp and plate converging toward each'other; a swinging lid on said cover plate; and a finger piece on said lid pro-- vided with a depending stop lip arranged to contact with said cover plate to prevent swinging 01" said lid beyond the vertical, substantially as described.

5. A bottle closure comprising a, cover plate to rest 'on top of the, bottle mouth; means for holding said cover plate in position on said bottle mouth; a swinging lid on said cover plate; and a finger piece normally projecting upwardly therefrom when closed for opening said lid and arranged on said lid to contact with said cover plate to prevent swing of said lid beyond the vertical, substantially as described.

6, A bottle closure comp-rising a cover plate to rest on top of the bottle mouth; a

depending flange on said cover plate; a

spring clamp secured to said flange, the lower edge of said flang being turned upwardly about said clamp and'there being beads struck from said flange to contact with the upper edge of said clamp; and a swinging lidon' said cover plate, substantially as clescribed.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOHN F. SLAPKA.
